Benefits of technology

[0006] Thus, there is need for a technique for increasing the capacity of a UMTS network at a relatively low cost.

Problems solved by technology

Generally, without tight coupling between the UMTS network and the wireless LAN, which is a fairly costly proposition, the UMTS network operator cannot effectively control subscriber access to the wireless LAN.
However, increasing the number of access nodes significantly increases equipment and deployment costs.

Embodiment Construction

[0009]FIG. 1 illustrates a block schematic diagram of a wireless communications system 10 in accordance with a preferred embodiment of the present principles. The system 10 includes a wireless network 12, which preferably has an architecture corresponding to that described in the well-known Universal Mobile Telephone System (UMTS) standard. Accordingly, the network 12 bears the designation “UMTS network.” Within the UMTS network 12, there exists at least one, and preferably, a plurality of macro cells, each comprising a radio access node 14 which is some times referred to as a “Node B.” Each radio access node 14 includes a radio transceiver (not shown) capable of exchanging both voice and data traffic with a mobile communications device 16 across a wireless link 17. The mobile communications device 16 can include a wireless telephony handset, a wireless Personal Data Assistant (PDA) or a personal computer having a wireless modem.

[0010] Within the UMTS network 12, each radio access ...

Abstract

A wireless telephony communications system includes at least one macro cell for communicating both voice and data with a mobile communications device across a first wireless link and at least one micro cell for communicating data with the mobile communications device across a second wireless communication link. Each micro cell communicates signaling information through the macro cell via a wireless link to a control element that manages the micro cells. Using a wireless link to communicate signaling between each micro cell and the control element in the UMTS system eliminates the need for a wired back haul link, thereby reducing access costs.

Description

TECHNICAL FIELD [0001] This invention relates to a wireless telephone network that affords improved access at relatively low cost. BACKGROUND ART [0002] Wireless telephony technology continues to evolve over time. Most recently, the European Telecommunications Standards Institute (ETSI) has promulgated a new standard for mobile telephony service, known as “Universal Mobile Telecommunications Service” or UMTS which offers broadband, packet-based transmission of voice, text, video and multimedia information at rates as high as 2 Mbs. The proposed UMTS standard describes a wireless network that includes one or more radio access nodes, each typically referred to as a “Node B.” One or more Radio Network Controllers (RNC) exist within the UMTS network to manage the radio access nodes. Each RNC has a broadband connection, typically in the form of an Asynchronous Transport Mode (ATM) Link, to a UMTS core network that provides Authorization, Authentication and Accounting (AAA) Functions.
